Volatility-Based Discounting
Volatility-based discounting is a quantitative approach where the value of collateral is adjusted based on the historical or implied volatility of the asset. Highly volatile assets are assigned a larger discount (or haircut) because they pose a greater risk of losing value rapidly, which could threaten the protocol solvency.
This method ensures that the collateral held by the platform is always sufficient to cover the position, even if the asset price swings wildly. Risk scoring models use this data to determine the margin requirements for different types of assets.
By applying these discounts, platforms create a tiered system where more stable assets are more efficient to use as collateral. This approach is essential for maintaining the stability of multi-asset collateral pools in DeFi.
